Running gametests in NeoForge 1.21.1

[rubensworks]

Hi 👋

Thanks for this GH Action!
I've been experimenting a bit with it, and while the action successfully runs and starts a client in a workflow, I can't seem to be able to get it to run any gametests.
And yes, there are game tests for those mods, which run when executing /test runall manually.

I always seem to get the following log output:

[10:50:23] [Render thread/INFO] [minecraft/Minecraft]: Running game tests...
[10:50:23] [Server thread/INFO] [me.ea.mc.McGameTestRunner/]: TestFunctions: []
[10:50:23] [Render thread/INFO] [minecraft/Minecraft]: No tests found, Successfully finished.

This is the workflow I'm testing with: https://github.com/CyclopsMC/packtests/blob/master/.github/workflows/gametests.yml
Latest workflow log: https://github.com/CyclopsMC/packtests/actions/runs/20877179977/job/59988251450#logs

Am I doing something wrong, or is there a bug somewhere?

So, as far as I understand it, the mechanisms to discover gametests depend on the modloaders and they are usually disabled for client sided mods, when running the production client instead of running from an IDE task.

We set up a small mod that showcases automatic gametest discovery for the production client: https://github.com/headlesshq/mcrt-gametests

As for actually bringing this to mc-runtime-test, it's very hacky, I'll have to look into this at some point.
